 Genetically Modified Organism (GMO) - Myths and Truths Genetically Modified Organism (GMO) - Myths and Truths  What are your thoughts on Genetically Modified Foods after watching this clip.

GENETICALLY MODIFIED MORE THAN 70 MILLION ACRES SINCE  Does not require labeling.  Process of breaking the natural boundaries that exist between species  Produces desired traits  Example: genes from salmon can be spliced into tomatoes to make them more resistant to cold weather HYBRIDIZATION  The fertilization of the flower of one species by the pollen of another species

 Hotly debated subject.  In the 1930s, Milford Beeghly created new hybrids of corn that were more resistant to insects and easier to grow than the original strain.  Many felt that this was against nature or immoral, but the hybrids proved to be commercially successful for the farmers that used them in their fields.

 More than ½ of America's processed grocery products contain gene-altered ingredients.  Splicing the genes makes the tomatoes crops larger when the weather is unfavorable.

 Refers to the way farmers grow and process agricultural products  Fruits, vegetables, grains, dairy, and meat.  Designed to encourage soil and water conservation and reduce pollution  Do not use conventional methods to fertilize and control weeds.  Use natural fertilizers, crop rotation, or mulch to manage weeds.

 View the video to the left and pay attention to the differences in the way that conventional and organic farmers grow their foods. What is Organic?

 No generally accepted definition of “local food”  Typically involve smaller farmers, heterogeneous products, and short supply chains  Farmer’s perform marketing functions: including storage, packaging, transportation, distribution, and advertising.
